Application filed March 20, 1917. Serial No. 155,997.

To all whom it may concern:

Be it known that I, LAUnrns Homvna citizen of the United States, residing at San Mateo, in the county of San Mateo and State of California, have invented new and useful Improvements in Reversible Windows, of which the following is a specification.

The object of the present invention is to provide a window of a type which can be reversed for the purpose of cleaning the same, and which, when in the closed position, will be perfectly water-tight and draft proof.

In the accompanying drawing, Figure 1 is a front view of one form of window to which my invention is applied; Fig. 2 is a side view on an enlarged scale of the lower sash of said window in its reversed position; Fig. 3 is a horizontal section of said sash on a still larger scale; Fig. 4 is a perspective view of an angular plate; Fig. 5 is a side View of a bolt; Fig. 6 is a broken vertical section of a portion of a sash on a still larger scale; Fig. 7 is a front view of another form of window to which my invention is shown as applied; Fig. 8 is a broken side view thereof; Fig. 9 is a broken View thereof.

Referring to the drawing, 1 indicates a window sill, and 2 window jambs, said jambs being each composed of a main piece 3 and an outer piece 4 secured thereon. The main piece 3 is formed with a rabbet 6, which, with the rabbet formed by the additional piece 4:, provides a double-rabbeted jamb to prevent passage into the apartment of water or strong currents of air. The narrow portion of the main piece 3 is formed with a vertically extending groove 7, in which is a slide-piece 8 secured to a round stem 9, which extends centrally through a cylindrical friction shoe 11, (Fig. 6).

Secured by screws 12 in the bottom of the wider portion of the main piece 3 of the jamb is a plate 13, (Fig. 1), and to said plate is pivoted, by means of a wide pivot 14 in the form of a rivet, the lower end of a flat bar 16, the upper end of which is similarly pivoted to a plate 17 secured by screws 18 to the adjacent side of a window sash 19, at about the middle of its length. Secured to each upper corner of the window sash is an angular piece formed out of sheet material, comprising a member 22 secured on the top of the sash, (Fig. 4) a member 23 secured against a vertical side wall of the sash, a substantially triangular portion 24 secured against the outer face of the sash, and a rectangular portion 26 secured against the inner face thereof. Through the member 23 is a round hole 27 through which extends the cylindrical friction shoe 11, one end of which is pressed against the window jamb by means of a spring 28 coiled around the stem 9, and compressed between a washer 29, abutting against the other end of said shoe and a portion 31 cut out, and depending, from the horizontal member 22, said stem 9 extending through a hole in said depending portion 31, and being swaged or riveted at its outer end to limit its movement outward from said hole. By means of the slidepiece 8, slidable vertically in the groove 7 in the jamb, it is insured that the end of the sash to which the angular piece is attached is always connected with the jamb, so that, if the bars 16 are swung outward from the room into the position shown in Fig. 2, since the end of the sash to which these angular pieces 8 are attached must move vertically downward, while-the center of the sash swings in a circle about the bottom of the window frame as center, the

result is that the sash is reversed, the said end being brought to the lowermost part, adjacent to said arms, and the bottom of the sash being uppermost. In order to hold the sash securely to the bars 16 in its reversed position, the horizontal member 22 is provided with a lateral extension 33, which is crimped or bent to form a guide-way for a bolt 34:, and has therein a bayonet slot 30, in which can slide a handle 35 attached to the bolt and in which it is retained when out of its locking position. Said bolt engages a longitudinally extending slot 38 in the bar 16.

In the modification of the invention shown in Figs. 7 8, and 9, which is adaptable for casement windows, the construction of the angular pieces at the tops of the sashes, and the parts connected therewith are the same as those used in the first form of the invention. But the bolts 34:, and the extension 33, for guiding the same, are now no longer required. In a recess in each bottom corner of the window sash there is contained a cylindrical tube 45, secured therein by a collar 36 having an extension through the vertical member of the angle iron and riveted thereto, and through said tube extends a vertical bolt 37 the upper end of which is bent at right angles and extends through a slot 40 in said vertical member. Said slot has a downwardly extending portion in which a handle 39 at the upper end of the bolt can drop when not in use. When in use, the handle is re moved from said downwardly extending portion, and is turned through an angle sufiicient to permit it to engage a vertical slot 41 of considerably greater length, so that said bolt can slide vertically through said tube 45 and drop into any one of a series of holes 44, in the bottom of a track 43 secured to the window sill, the track being also provided with drain holes 46 to permit moisture to escape therefrom. The window jamb is also provided with a recess 47 to receive the projecting head of the handle 39. The bottom of the tube 45 is enlarged to form a shoe 42 to move in said track 43.

In this modification the shoes are pressed against the transom rail 48 by means of a bow spring 49, through holes in which the stem 9 passes said bow being compressed between a portion 51 of said angular piece and the washer 29.

I claim 1. In combination with a window frame having vertical grooves in its side members, a sash, bars pivoted at one end to mediate portions of said sash and at the other end to the window frame, shoes carried by portions of said sash remote from said bars,

springs pressing said shoes against the sides of the window frame, stems slidable through said shoes, and slide-pieces on said stems slidable in said grooves.

2. In combination with a window frame, a sash therefor, bars pivoted at one end to mediate portions of said sash and at the other end to the window frame, angular pieces secured to corners of said sash, shoes guided by said angular pieces, stems slidable through said shoes, slide-pieces carried by said stems are movable in said grooves, and springs coiled around said stems and compressed between said shoes and portions of said angular pieces, and pressing said shoes against the sides of the window frame.

3. In combination with a window frame, a sash therefor, bars pivoted at one end to mediate portions of said sash and at the other end to the window frame, angular pieces secured to corners of said sash, shoes guided by said angular piece, stems slidable through said'shoes, slide-pieces carried by said stems and movable in said grooves, springs coiled around said stems and com-- pressed between said shoes and portions of said angular pieces, and pressing said shoes against the sides of the window frame, said angular pieces forming bolt guides, and bolts in said guides and adapted to engage portions of said bars.
